Ummm, these were in your engine like that? You didn't notice the misfiring???

I didn't. I'm not sure it was - that was #6's plug, I really wasn't even planning on changing em, I just happen to be right there and was curious so I pulled it. I just swapped it for a plug from the '98 for now, less than 5k on em so kinda new-ish I guess. I had to pull another after discovering that though. I pulled #4 and it was completely covered in oil ! Craptastic. It wasn't smashed on the end or in so tight as to require a breaker bar so I guess that's a little better... maybe. This wasn't going to well. I pulled #2 and it was ok, same with #8

I stopped there for the time being because I got more pertinent issues right now (starting a new thread about it in a few)

Would that plug definitely be misfiring in that condition? I've never had any codes for anything like that.
And it's been in there for two years or something ever since i bought it at the Cadillac dealership.... Crazy, huh. At least they all weren't like that, who knows about the other four though

Re: Hey, what are spark plugs supposed to be torqued to...?

I don't think that's from being overtorqued. The electrode shouldn't bottom out on the cylinder head. Maybe it got too hot and soft and "melted" like that. Or whoever put it in dropped it beforehand and said "fook it".
